Brain Boosters
Week of September 18

Today's tip prompts you to check out some new music. This week's Brain Booster shows you that the oldies but goodies get your toes tapping too!  Belt out the lyrics to the songs below and earn a point for each one whose artist and singer you can name. Extra points if you sing the choruses too!

1. Winter, spring, summer or fall

All you've got to do is call

And I'll be there, yeah, yeah, yeah


2. But what it is

Is something true

Made up of these three words

That I must say to you 


3. Let us realize

That a change can only come

When we stand together as one

(By the way, all of us at the KU ADRC dedicate these songs to all of you!)


  1. You’ve Got a Friend by James Taylor (by the time you read this, fall will be just days away!)
  2. I Just Called to Say I Love You by Stevie Wonder (we feel this way on World Alzheimer’s Day and always)
  3. We are the World by USA for Africa (as other lyrics in the song say, we are the ones who make a brighter day – and we are working on empowering the whole world with good brain health!)

Week of September 4

Happy September! This new month brings a new season – autumn, with its cooler temperatures, colorful trees and chances to celebrate our team spirit.

For this week’s Brain Boosters, we’re bringing you some new fun facts and dates to remember:

1. Which one is not happening in September?

    1. Read a New Book Month
    2. International Square Dancing Month
    3. National Piano Month

In August 1988 - 35 years ago - then-President Ronald Reagan proclaimed August 21 to be National Senior Citizens Day! You may not have been a senior then (or now), but we can all honor older adults for the expertise, perspective and care they share. 

In honor of this special day - and ahead of our weekly webinar on honorable aging -  boost your brain by answering these questions:

1) What age do you have to be to be a senior/older adult?

3) True or false: dementia is a normal part of aging.

Bonus question: what are some tips for healthy aging? 


  1. g: any or all of the above! At age 50, you can join AARP and receive discounts, services and other benefits; at 55, many retailers offer senior discounts. Once you’re age 60, the federal Older Americans Act ( means you can receive supportive services like home-delivered meals, in-home care, caregiver support, job training and more. Social Security retirement benefits can begin at age 62 (some people may choose to delay them in order to eventually receive more money).  Medicare eligibility starts at 65 for most people. And if none of these resonate with you, you can designate any year you like!
  2. Jeanne Louise Calment is the oldest verified person to have ever lived. The Frenchwoman lived to be 122 years and 164 days old. She was born on February 21, 1875 and passed away at age 122 on August 4,  1997.
  3. False. Dementia (of the Alzheimer or any other type) is not a normal part of aging.

You've been inspired! After participating in this week's Weekly Webinar (and watching some of our other recordings about exercise, fitness and brain health), you might consider getting a book about physical activity from the library or bookstore. But if you see a book with How to Jog printed on its spine, you actually shouldn’t check it out. Why not?


How to Jog is an encyclopedia volume (remember those?)! It simply carries entries of words that begin with How to words that begin with Jog.

This week we’re giving you tips on advocating for yourself and a loved one, and speaking up for what you need. Our brain boosters will have you thinking about speaking – raise your voice and give them a try!

A worker went into the office one day and spoke only Italian. Everyone could understand what the worker was saying and didn’t have any problems understanding. It was a perfectly normal day. How? Why?

I have no voice, yet I speak to you,

I tell of all things in the world that people do.

I have leaves, but I am not a tree.

I have a spine and hinges, but I am not a human or door

I have told you all – I cannot tell you more.

What am I?

Two speakers are on an upcoming schedule. Using the list of presenters below, identify which of them will talk today and which tomorrow.

Hint: the answer is a common idiom.

Today’s Speakers:

  • Professor Present
  • Representative Right
  • Honorable Here

Tomorrow’s Speakers:

  • Lecturer Later
  • General Gone
  • Faculty Future

    The worker was in Italy!

    A book

    Honorable Here and General GoneHere today and gone tomorrow!

    Week of May 15:

    Prepare to be a-MAZEd by this week's Brain Booster! To align with our Weekly Webinar about Seeking Clarity in the Labyrinth, this week's challenge is to find your way through a maze. 

    This website has lots of mazes from easy to hard - you can do them on your device or print them and use a pen or pencil. If you do one on your device, the website will tell you how much time you took and how many steps you made. On one practice run of a medium-level maze for the MyAlliance team, it took 79 seconds and 170 steps. How will you do?

    Do you know the difference between a maze and a labyrinth?


      Solutions to the maze you choose to do will vary depending on which maze you pick and which path(s) you take. Enjoy challenging and boosting your brain!


      Though the terms are often used interchangeably, mazes and labyrinths have slightly different definitions. Officially, the word maze refers to a collection of branching paths, through which the traveler must find the correct route. Labyrinth, meanwhile, refers to a pathway which, while winding and potentially disorienting, is non-branching, and leads directly to its endpoint.


      *Unicursal describes something that has a single continuous path or line.

        Week of March 13:

        This weekend we moved our clocks ahead one hour to spring forward into Daylight Saving Time. Boost your brain by determining if these statements are true or false:

        1. True or False? Two US states do not observe Daylight Saving time. 
        2. True or False? Daylight Saving Time begins at the stroke of midnight on the appointed day.
        3. True or False? Farmers and department stores find great benefits in Daylight Saving Time.


        1. True – Hawaii and (parts of) Arizona do not observe Daylight Saving Time.

        2. False – Daylight Saving Time begins at 2:00 am local time – the idea is that most people will still be at home or even asleep for the night and most businesses will be closed.

        3. False – While department stores have found that more daylight is good for business because more people go shopping, farmers opposed it from the beginning because it wreaks havoc with their schedules, they have to wait for the dew to evaporate off the hay in the morning, regardless of what time it is, and it throws the cows off!

          Here's a fun way to exercise different lobes of your brain.   Count the number of times the number "6" appears below.  Now count the total number of times a "3" or a "7" appears as you see them. (In other words, don’t just count all the “3“s, and then the “7“s; count both at the same time as you see either one.)  For example, the number of times a 3 or a 7 appear is this sample, "763537" is 4 times.


          The important thing here is not so much to get the right answer, but to exercise your frontal and parietal lobes by trying.

          Answers: “6” appears 33 times, and the total times the numbers “3” and “7” appear is 59 times.

          Week of October 17th: 

          Below are pairs of words, and your goal is to find a third word that is connected or associated with both words.

          Try your luck with the following words.

          1. SHIP and CARD
          2. SCHOOL and EYE
          3. PILLOW and COURT

          Week of August 29th: 

          Gretchen and Henry were looking to buy a house together, and finally found one with a beautifully landscaped yard, plenty of bedrooms, and a beautiful tree out front. They asked the owner how old the house was, and this was his reply:

          "I planted that tree when the house was built. It was 7 feet tall at the time. It has grown 3 feet each year, and at the end of this past full year, it was four times its original height."

          "But how old is the house?" asked Henry.

          Gretchen said, "Don't be so dense. He just told us."

          So, how old is the house?


          The house is 7 years old.
          The tree height is 28 feet, since it is four times its original height.

          To figure out the age of the tree, let x = age of the tree in years. The height of the tree is then 7 + 3x. Since we know that the tree is now 28 feet, we can say:
          28 = 7 + 3x
          21 = 3x
          7 = x

          So the tree must be 7 years old, making the house just as old.

          A fly and a flea are trapped in a flue.

          How far must the fly and the flea fly to flee the flue?
          Said the fly to the flea 'to flee is some number times 3.'
          Said the flea to the fly 'but 3 squared is too high.'
          Responds the fly 'but it'll also do to have some number times 2.'
          'Agreed' said the flea. 'Then so it shall be.'
          So now it is up to you. How far must the fly and the flea fly to flee the flue?

          Answer:  6 units (pick your own)
          3 squared is too high, so we know it is less than nine. Since 3 and 2 are factors there is only one number less than 9 with that property.

          We start with what a pen can write
          Then add an "s" for a tool of lesser might

          Change "d" to "n" for an oath professed
          Remove letter one for a condition no longer the best

          Change "w" to "t" for something forced apart
          Reverse my ends, then add an "h" for what's atop a chart

          Change "n" to "w" to learn how much an item can fetch
          Finally, anagram me for what in baseball may follow a stretch

          What did we start with?
          What do we end up with?


          Each line of this riddle is explained as follows:

          1. word - We start with - A "pen can write" a word.
          2. sword - Then add an "s" - "for a tool of lesser might" - This alludes to the adage: "The pen is mightier than the sword."
          3. sworn - Change "d" to "n" - "for an oath professed"
          4. worn - Remove letter one - "for a condition no longer the best" - If something is worn, then its condition has deteriorated.
          5. torn - Change "w" to "t" - "for something forced apart"
          6. north - Reverse my ends, then add an "h" - "for what's atop a chart" - Switch the first and last letters of "torn" giving "nort", then add an "h" giving "north". "North" (or "N" representing "North") is usually found at the top of a chart.
          7. worth - Change "n" to "w" - "to learn how much an item can fetch" - The worth, or value, of something will determine how much money it can get in exchange for it.
          8. throw - Finally, anagram me - "for what in baseball may follow a stretch" - "Throw" is an anagram of "worth". In baseball, the pitcher may throw the ball after a certain windup known as a stretch.

          A firefighter stood on the middle rung of a ladder, spraying water on a burning house. He then climbed up 6 rungs before the heat of the flames caused him to come down 10 rungs. After some minutes he was able to climb 18 rungs to the very top of the ladder. How many rungs did the ladder have?


          29 rungs
          The firefighter is standing on the middle rung. He climbs up 6 rungs, so he is now at Middle+6. He then goes down 10 rungs, so he is now at Middle-4.  He goes up 18 rungs, so he is now at Middle+14=Top. 14 rungs from the top, 14 rungs from the bottom and the middle rung. 14+14+1=29!

          The five words in the group below have something special in common.  They can be transformed into five new words by applying the same exact change to each word. What is the change and what are the resulting five new words?


          Answer:  The special thing these words have in common is that when each word is prefixed with the letter "f", the result is a new word that is completely unrelated in meaning to the original word, as follows:

          f + action becomes the word faction
          f + allow becomes the word fallow
          f + lawless becomes the word flawless
          f + lower becomes the word flower
          f + rail becomes the word frail

          Four people arrive at a river with a narrow bridge that can only hold two people at a time. It’s nighttime and they have one torch that must be used when crossing the bridge. Person A can cross the bridge in one minute, B in two minutes, C in five minutes, and D in eight minutes. When two people cross the bridge together, they must move at the slower person’s pace. Can they all get across the bridge in 15 minutes or less?

          Answer: Yes, they can cross in exactly 15 minutes. The group of four must follow these three steps.

          1. First, A and B cross the bridge and A brings the light back. This takes 3 minutes.

          2. Next, C and D cross and B brings the light back. This takes another 10 minutes.
